This is a huge mistake:
Kerry: Vets' book should be withdrawn: 'Unfit for Command' publisher distributing 'falsehoods,' 'smear'

Sen. John Kerry's campaign is calling on Regnery Publishing to withdraw a best-selling book by a veterans group challenging the presidential candidate's Vietnam war record

Kerry campaign spokesman Chad Clanton told Salon.com

“No publisher should want to be selling books with proven falsehoods in them, especially falsehoods that are meant to smear the military service of an American veteran,”

Rather than ask for censorship, Mr. Clanton would be better at his job if the campaign had focused on the war we're fighting today. By focusing on Vietnam, Kerry made a critical mistake. Asking for censorship only makes it worse. If the Unfit For Command book is stating "proven falsehoods", then address the issues the book raises.
Don't go calling for the book's withdrawal.
